An 81-year-old homeless male is brought to the ER due to symptoms of psychosis. The PMHNP is unable to obtain a history from this patient and thus relies on his medical record. The record indicates that the patient left the hospital against medical advice one week ago because he was not happy with the diagnosis of renal stones he received. At that time, he wanted help with his flank pain and did not like how he was treated, so he left before a thorough work-up could be completed. At this visit, the PMHNP notes the ER team was able to order labs and obtain a urine sample due to having to insert an indwelling catheter for urine retention.
